// *****************************************************************************
//
// CLASS DESCRIPTION (MFnLight)
// 
// MFnLight allows the creation and manipulation of dependency graph nodes 
// representing lights.  This is the top level of a hierarchy of light 
// node function sets.  It permits manipulation of the attributes common to
// all types of lights.
